BOTTLE-CLOSURE.

To all whom it may concern Be it known that I, LUDWIG W. ZAAK, a formersubject of the Emperor of Austria, who have declared my intentionofbecoming a citizen of the United States, and a resident of the city ofChicago, ycountey of Cook, and State of Illinois, have invented certainnew and useful Improvements in Bottle- Closures, of which the followingis a specification.

My invention relates to closures for bottles, and like containers, andhas for its object the production of a container equipped with a closureadapted, when the container is lifted from position uponthe table top orother supporting surface, to automatically move to open positionand,when the container is returned to position upon the table top, or othersupporting sur-face, to be -automatically moved to closing position.

A further object is the production of a device as mentioned which willbe of simple and economical construction and eflicient in* use.

Other objects will appear hereinafter.

With these objects in view, the invention consists in the combinationsand arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawing forming a part of this specification, and in which,

Figure 1 is a central vertical section. through a bottle equipped with aclosure provided with a closure 2 which is hingedly or pivotallyconnected with the body 1 at 3.

Said closure is provided, at the point of its pivotal .connection withthe container body, with a laterally extending finger 4. Cooperatingwith the closure isa vertically disposed rod 5 the upper end of which ispivotally connected with the outer end of-finger 4. The lower end of rod5 projects loosely Specification of Letters Patent.

through a passage 6 formed through the body 1, and is provided at itslower end with a weighted head 7. The weight of said rod 5 and the head7 thereof is such as to normally hold the closure 2 in open position,the head 7, when said closure is in this position, projecting below thebottom surface vof the body 1, as clearly shown in Fig. 2. A helicalcompression spring 8 interposed between the head 7 and a shoulder'9'formed in the passage 6, assists the rod 5 i-n normally assuming theposition shown in Fig. 2. in order to normally hold the closure 2 inopen position, as mentioned. The arrangement is such, however, that whenthe container is placed upon a table top or other supporting surface,the head 7 will contact with said surface or table top, and be movedupwardly to cause. rocking of the closure 2 to closing position, asshown in Fig. 1. With this arrangement then, it will be seen that, inuse, when the device is in upright position upon a table top or othersupporting surface, the closure thereof will`be in closed position, but,upon lifting of the ldevice from the table top or supporting surface foruse, said closure will be automatically rocked .to open posi- 'tion soas to permit ofthe contents of the container being discharged.

The upper end 4of the rod 5 is provided with an extension 10 upon whichis mounted y a finger 11 adapted for rotary adjustment. Said ,finger 11is adapted, ,when in engagement with the closure 2, as shown in F1g. 1,to prevent rocking of the latter to open position, said closure beingreleased f for opening movement by adjusting said finger out ofengagement therewith, or to the po- Lsition shown in Fig. 2. With this'arrangement, it willpbe seen that, when desired, the closure of thecontainer may be locked in closed position so as to prevent "actuationthereof by the rod 5.

The closure 2 1s preferably of the form A shown, being formed at itsunder side with a central plug portion 12 which is adapted to snugly fitthe mouth end of the body 1,

the periphery-of said closure being adapted at the same time to engagewith the shoulder 13 of said body. Said closure engaging with the mouthof the container body at two points, insures an absolutely tightconnection when said closure is in closed position.

While I have illustrated and. described Y g l 1,129,018

the preferred form of construction for carrying my invention intoeffect, this is capable of variation and modification without departingfrom the spirit of the invention. I, therefore, Ido not wish to belimited to the precise details of construction set Y forth, but desireto avail myself of such variations and modifications as come within thescope of the appended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:4

1. A device of the class described comprising a container; a hingedclosure for said container; a vertically movable rod connected at itsupper end with said closure, said rod being adapted, when at its lowerterminal of movement, to hold said closure in open position, said rodpassing loosely through a passage formed in said container, the lowerend of said rod, when at its lower terminal of movement projecting belowthe bottom surface of said container and a helical compression springarranged in said passage and coperating with said rod to normally holdthe latter at its lower terminal of movement, substantially asdescribed.

2. Ay de ce of the class described comprising. a container; a hingedclosure for.

said container; a vertically movable mem- `ber connected with saidclosure for moving said closure to closing position, when said containeris placed upon a supporting surface, and for moving said closure tokopen position, when the container is lifted from position upon thesupporting surface; and a manually adjustable finger mounted for rotaryadjustment at the upper end of said member, adapted for releasableengagement with said closure for locking the same in closed position,substantially as described.

In testimony whereof I have signed my name to this specification `in thepresence of two subscribing witnesses.
